Government shares in total output are characterized by significant variation across countries. I noticed a strong negative correlation between government consumption shares and the price of government services in terms of private consumption. Motivated by this empirical observation, I developed a neoclassical growth model with added government that is capable of matching the variation in government shares very closely using only relative prices. In addition, I provide empirical evidence showing that the relative price of government consumption increases with income, which is consistent with distortions prevailing in poor countries. These two observations combined imply that government shares tend to be higher in poorer countries.

This paper investigates whether remittance inflows reduce the elasticity of government size with respect to trade openness. Put differently, the paper tests the hypothesis that there is a partial substitution between public insurance through government spending and a private insurance through remittances in more open countries. The insurance role of remittances is evaluated by computing annual panel data coefficients of remittance cyclically with respect to the real GDP cycle. It appears that remittances have become more countercyclical during the end 1990s. Moreover, the trade openness, natural disasters, inflation and the shallowness nature of the financial system are among the main determinants of the countercyclicality of remittance inflows. From a simple theoretical model close to Rodrik (1998) and on the basis of econometric estimations using a large sample of developing countries (66), it appears that the positive impact of trade openness on government spending decreases with the level of remittances received. Moreover, it is when remittances are effectively countercyclical that the mechanism described here works.
